BACKGROUND OF THE INVENTION

This invention provides a smart liquid container apparatus and method providing for opening and closing a smart cap without detaching the smart cap from the container body.

The prior art does not provide for an oil container, or a related liquid container, apparatus and method providing a smart cap with a smart-cap opening turnably mounted upon an opening protrusion on a container body such that the smart cap can be closed and opened without detaching the smart cap from the container body, consequently preventing misplacement or loss of the smart cap and simplifying the use of the container. With the currently available fluid (e.g., motor oil, anti-freeze, transmission oil, etc.) containers on the market today, when the user needs to add fluid to the engine, for example, he or she must either use a funnel to avoid spilling of the liquid or make their best effort to prevent the liquid from spilling during the pouring process; but unfortunately, more often than not, the liquid will spill and contaminate other components of the engine. While this is seemingly a benign issue, it may certainly result in a disastrous outcome for the user or even others. For instance, if oil spill contaminates the alternator, then the spilled oil might ruin the alternator. Aside from the cost and inconvenience of replacing a ruined part, the malfunction of the alternator will cause the vehicle to stall, and perhaps without warning. Moreover, if such an incident occurs in a high traffic and/or high-speed area, it could result in serious or fatal injuries to the operator of the vehicle and others as well.

For example, U.S. Pat. No. 9,714,123 for a “Dispensing Closure,” issued on Jul. 25, 2017 to assignee Again Innovations Ltd., provides for a dispensing closure for covering an opening of a container including a liquid. The dispensing closure includes an engagement element that fits over the opening of the container and defines a pouring orifice for allowing pouring of the liquid. The pouring orifice having a side defining an air channel for allowing air to flow into the container when liquid during the pouring. The engagement element also includes outer walls and a cap having a hollow including inner walls tightly conforming to the outer walls, a first orifice generally conforming in shape to the pouring orifice, and a second orifice generally conforming in shape to the air channel.

U.S. Pat. No. 6,494,344 for a “Liquid Dispensing Container,” issued on Dec. 17, 2002 to inventor Joseph A. Kressel, Sr., provides for a liquid dispensing container for conveniently storing and dispensing various types of fluids. The liquid dispensing container includes a container capable of storing a volume of fluid, a strap attached to an upper surface of the container, a fill cap removably attached to a threaded nipple, a transparent or semi-transparent viewing portion within at least one side of the container, a dispensing hose fluidly connected to a lower portion of the container, a dispensing nozzle attached to the end of the dispensing hose, and a clasp attached to the container for catchably receiving the dispensing hose. A plurality of marker lines and relevant indicia are preferably positioned adjacent the viewing portion which has an elongate vertical structure thereto for allowing an individual to determine the amount of fluid within or dispensed from the container. The dispensing hose and the nozzle are preferably comprised of a relatively smaller structure for allowing the individual to fit the nozzle into compact areas.

U.S. Pat. No. 6,082,591 for a “Graduated Sight Glass Container,” issued on Jul. 4, 2000 to inventor Thomas J. Healey, provides for a graduated sight glass container for retaining a substance therein and minimizing the possibility of spillage during dispensing of the substance therefrom. The graduated sight glass container includes a housing having a shape of a quadrilateral and including an indented section on a first side thereof. A spout is connected to extend from the indented section of the housing and at most up to the first side. A pool is formed within the indented section and surrounding the spout, wherein, when the container is tilted from a vertical at-rest position causing the spout to be positioned adjacent an opening through which the substance contained within the container is to flow, the pool is caused to at least partially receive an edge of the opening. Extending along a second side of the housing is a first graduated scale and a second graduated scale extends along a base of the housing for measuring an amount of the substance within said container and an amount of the substance dispensed from the container during dispensing. The first and second graduated scales are both made of a clear material allowing a user to view the substance within the container therethrough and include indicia printed therealong indicative of a volume of said container at predetermined positions.

U.S. Pat. No. 3,198,406 for a “Dispenser Cap with Deformable Cone Assembly,” issued on Aug. 3, 1965 to inventor Ahron W. Kopelman, provides for a dispenser cap having controllable valve means for dispensing liquids or pastes from a container, and more particularly, a dispenser cap comprising an outer cap rotatably retained on an inner cap, the outer cap having a resiliently expandable conical sleeve to permit assembly to be achieved by elastic deformation.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, the smart liquid container 10 apparatus of the invention comprises a container body 1 to safely hold oil and similar heavy, viscous liquids, having a top, bottom, and sides, with a container handle 6 at or near the top of the container body, for safe carrying and manipulating of the container, and having, optionally, volume indicators 8 showing the volume of oil or similar fluids in the container. Also, at or near the top of the container body is placed a sealable air vent 7, which, when opened, prevents any vacuum lock from hampering the flow of liquid. The container body 1 is made of a clear or translucent material allowing a user to visually ascertain the volume of liquid within the container by reference to the volume indicators 8. The container body 1 is of a shape that allows resting or temporary placement of the smart liquid container 10 upon or near the engine, above the engine's liquid inlet such as an oil inlet. The container body 1, especially at the bottom should be able to withstand the consequent heat of the engine, and the bottom should have a flat, stable profile.

Referring additionally to FIG. 2, on a side, and near the bottom of the container body is placed an opening protrusion 2 having threads which tend to pull an encircling object closer or push it away when turned in different directions. Upon the opening protrusion 2 is placed a body opening 3 which, when unsealed, allows the flow of liquid out of the container body 1.

Referring additionally to FIG. 3, a smart cap 4 is provided to be mounted upon the opening protrusion 2 such that, when turned in one direction, the smart cap is pulled toward the container body, and the body opening 3 is sealed, preventing the flow of liquid; and when turned in the opposite direction, the smart cap is pushed away from the container body, and the body opening 3 is unsealed, allowing the flow of liquid. A smart-cap opening 5 is provided to allow liquid flowing from the body opening 3 to pass out of the smart cap 4 when the smart cap 4 is in an open position.

Referring to FIG. 4 and FIG. 5, in use in a closed position, the smart cap 4 is held tight against, and blocks or seals, the body opening 3 in the opening protrusion 2. The smart-cap opening 5 therefore cannot pass any liquid, and the location of the smart-cap opening does not have any effect upon the non-existent flow of liquid.

Referring to FIG. 6 and FIG. 7, in use in a partially open position, the smart cap 4 is moved slightly away from the body opening 3 in the opening protrusion 2, and a partial flow of liquid is allowed. The smart-cap opening 5 moves into a position allowing a partial flow of liquid through the smart cap 4. This allows a user to control the rate of outflow of the liquid.

Referring to FIG. 8 and FIG. 9, in use in a fully open position, the smart cap 4 is moved farther away from the body opening 3 in the opening protrusion 2, and a full flow of liquid is allowed. The smart-cap opening 5 moves into a position allowing a full flow of liquid through the smart cap 4.

During use, the smart cap 4 is not removed from the opening protrusion 2 of the container body 1. The smart cap 4 is easily, conveniently, and safely manipulated to deliver a precise flow of liquid, even in awkward positions; and the smart cap 4 cannot be misplaced but is always at hand to be turned again to stop or modulate the flow of liquid.
